I’m planning to launch a secure, web-based application that offers the same core experience users expect from [login to view URL]: create an account, sign in, and start storing or sharing files straight from the browser. From database design through front-end polish, I need a full-stack partner who can deliver a reliable MVP and guide the technical choices along the way. The heart of the project is rock-solid user authentication (email/password, with room for social logins later) and a smooth file-management workflow. Once logged in, a user must be able to upload, organize, preview, download, and share files through an intuitive interface, all backed by a scalable storage layer. Security is non-negotiable—TLS everywhere, encrypted files at rest, and sensible permission levels so folders and links stay private unless explicitly shared. I’m comfortable with any modern stack—React or Vue on the front end, Node/Express, Django, or a comparable framework on the back, storage on AWS S3, GCP, or Azure—but I’m open to your best recommendation as long as it keeps costs predictable and future-proof. Deliverables • Source code in a Git repo with clear build instructions • Deployed MVP accessible via a public URL • Brief hand-off document covering architecture, environment variables, and how to add new features If you’ve built authentication flows or file-sharing portals before, let’s talk.

OVER 10 YEARS OF EXPERIENCE IN FULL-STACK WEB DEVELOPMENT & CLOUD ARCHITECTURE Hey there! One of the biggest challenges with a project like this is striking the perfect balance between bulletproof security and a seamless user experience—and that’s exactly where I can help. I’ve built authentication systems, file-sharing dashboards, and cloud storage workflows before, so I know how to avoid common pitfalls like clunky login flows, permission leaks, or slow file previews. For your app, I’d recommend a modern stack (React + Node/Express or Django) with storage on AWS S3, making sure uploads, previews, and shares feel instant while everything stays encrypted and properly permissioned. I’ll design the database schema to scale, implement clean and secure auth with room for social logins later, and wrap it all in an intuitive interface that doesn’t overwhelm users. You’ll get a deployed MVP, clean repo, and clear documentation so you’re never locked in. Think of it as building your own secure “mini-Box” but leaner, future-proof, and totally under your control. Let’s make this solid and ready for real-world use! Best regards, Truong Pham.

Hi jalakd111, I recently completed a very similar project. I can show u sample. Questions: 1) What is the target permission/sharing model at MVP: personal accounts only, or org workspaces with teams and hierarchical ACL inheritance? Should shared links support scope (org-only/public), expiry, passwords, watermarking, and external-collaborator access? 2) What are the upload/preview/compliance constraints: max file size and concurrent uploads, file types needing in-browser preview (images, PDF, Office, video), CDN/geolocation/data residency, and whether AV scanning, DLP, or legal hold/audit export is required? Suggestions: 1) AWS-first architecture: Nextjs (React) + Authjs (email/password now, WebAuthn/social-ready), Postgres (RDS) + Prisma, S3 + SSE-KMS, CloudFront (OAC) Use S3 multipart presigned uploads with client-side checksum and resumability; store only metadata in DB Async pipeline via SQS+Lambda for AV scan (ClamAV), thumbnails/transcodes, and to finalize object state Short-lived, httpOnly cookie sessions with rotating refresh tokens 2) Robust model and sharing: Materialized-path folder tree; item_version and item_acl tables with inherited grants cached per node Content-addressed storage (SHA-256) for dedupe and immutability; S3 versioning enabled You send me a message ok, lets discuss and btw my portfolio is uploaded here and on my website.
